Preheat one or two nonstick skillets over medium heat. Pour all the dry ingredients into a large mixing bowl and whisk. Then add the milk, egg, vanilla, melted butter, and strawberry jam. Whisk until smooth. If using squirt bottles for pancake art, stir in another 1/4 cup of milk and do not add the fresh strawberries into the batter. If making normal pancakes, fold in the fresh strawberries.
For Pancake Art: Pour the thin batter into plastic squirt bottles. Make sure the hole in the lid is the size of a bb. If not, trim the end with scissors. Butter the skillet, then slowly squirt the batter into the shape of a heart. Use the batter to make a pattern inside the heart: dots, stripes, zigzags. Then wait an minute and fill in the open areas inside the heart. Wait another minute, then flip the pancake(s) and cook another 1-2 minutes. Repeat and have fun making designs!
If making classic pancakes, ladle 1/4 portions of the batter into the skillet(s). Cook for 2-3 minutes per side. Then butter the skillet and repeat. Serve with maple syrup or strawberry jam, and a side of heart shaped bacon and eggs.
